SUCTION-SWEEPER.

Specification of Letters Patent.

Patented Apr. 23, 1918.

To all whom z'tmay concern:

Be it known that I, HOWARD EARL Hoovnn, a citizen of the United States res1d1ng at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in' Suction-Sweepers, of which the following is a specificatlon.

y invention relates to means for supporting the upper end of the bag on a suction sweeper so as to prevent the ba from dragging on the floor or getting un er the Wheels of the sweeper proper.

The particular object is to support such upper end of the bag in its proper pos1t1o n to prevent dragging, regardless of the position of the handle and regardless of the condition of the bag, whether it be filled or not.

The invention consists in means for hanging the upper end of the bag so that it may automatically or by hand be moved along the handle and retained normally at either end of its sliding excursion. The invention consists further in various details of construction set forth. It is illustrated in the accompanying drawings wherein Figure 1 is a side elevation of the eviction sweeper'containing one form of my invention with the handle inclined.

Fig. 2 is a side elevation of the same with the handle in an upright position.

Fig. 3 is a side elevation of the modified form of the suspended device.

Fig. 4: is a side elevation of the same form with the handle in an upright position.

Fig. 5 is a detail of a modified form of the guide.

Like parts are indicated by the same let ter in all the figures.

A is the sweeper proper to which is ivotally attached the handle B. C is a long having at its lower end means whereby it is connected at C with the dust discharge passage of the sweeper. D is a link attached to the center of the bag end at D D is a hook which will seize the upper end of the link and is provided with the e e D slidable on the gulde D on the han le B.

This guide is parallel with but separated from the handle. It is preferably protvided at its upper end. In the modified form of Figs. 3 and 4 the link takes the form of a ringD which is adapted to one .ed e .of the bag end and directly engages the ook.

' and for as soon as the machine is in This involves the use of a longer ide therefore is not the preferred i rm. The loop in the guide may be dispensed with but'when in this form there isno provision for holding the bag when it is in the position of Figs. 1 and 3 and deflated.

It will be understood, of course, that my drawing is to be taken as diagrammatic although it is a fairly faithful representation of the actual structure. I do not Wish to be limited to the particular form, shape, proportion and arrangement of parts here illustrated.

The parts D, D and D together constituethe bag support which is slidably mounted upon the guide.

The use and operation of my invention is as follows:

" When the sweeper is out of use it preferably stands in the position of Figs. 2 or 4 and the ring or link together With the hook is at the lowest point of the excursion of the hook. The bag is properly supported in each case and it is not intended to drag on the floor. If, handle be thrown end of the bag can be until the hook falls into the loop. This action will result from indating the bag in either form of the device operation, the air passing into the bag from the sweeper tends to distend the bag and throws its upper end upwardly and outwardly along the handle until the hook drops into the loop. in this position the bag is carried free from the ground whether it be empty or full, inflated or deflated and moved forwardly or backwardly. When the handie is tilted from the inclined to the upright position the hag, whether full or empty, inflated or deflated, will slide the hook down along the guide the moment it is freed from the loop until the hook lies at the lower end of its excursion.

In the modified form of Figs. 3 and 4 no advantage is taken of the increased length of the bag owing to its deflation and it is necessary to have a longer guide.

In thecase of a flat bottomed ba the upper end of the guide or securing evice is, under the normalconditions of operation, approximately in the plane of the bottom of the hag. The eflect of this-is that when the bag is inflated and the handle in this the ing a han e, comprlsmg normal position as illustrated in Fig. 1, the bottom of the bag forces the securing bag support up and alon and finally to the upper end of the gui e, where, if there be a loop, it drops into the loop. This would not necessarily occur with a bag not having a flat bottom or with a guide not positioned. When the parts have t us been operated and brought into the position in Fig. 1, the parts will remain in this position, and the machine can be moved around. The bag will not sink back into its unsupported condition the moment it is deflated. On the contrary, it will remain in the position indicated being held out of contact with the floor.

I claim:

1. A bag holder for a suction sweeper having a handle, comprising a guide adapted to be secured on substantially parallel with, and slightly removed from the handle, a bag support adapted to be secured to the upper end of the bag and slidably mounted on the guide.

2. A bag holder for a suction sweeper having a handle, comprising a guide adapted to be secured on substantially parallel with, and slightly removed from the handle, a bag support adapted to be secured to the upper end of the bag and slidably mounted on the guide and means at the upper end of the guide to retain the slidable part at the upward end of its excursion.

3. A bag holder for a suction sweeper having a handle, comprising a guide adapted to be secured on substantially parallel with, and slightly removed from the handle, a bag support adapted to be secured to the upper end of the bag and slidably mounted on the guide and a oop at the upper end of the guide to retain the slidable part at the upward end of its excursion.

(l. A ba holder fora suction sweeper hava guide adapted to be secured on substantlally parallel with, and

slightly removed from the handle, a bag properly the upper the upper end of the bag in combination with .g bag having a substantially flat, upper end. 5. A bag holder for a suction sweeper having a handle, comprising a guide adapted to be secured on substantially parallel with, and slightly removed from the handle, a bag support adapted to be secured to the upper end of the bag and slidably mounted on the guide and means at the upper end of the guide to retain the slidable part at the upward end of its excursion, said bag support containing an extension approximately e ual to the radius of the cross section of the ag and adapted to be secured approximately to the middle of the upper end of the bag in combination with a bag having a substantially flat upper end.

6. A ba holder for a suction sweeper having a han le, comprising a guide adapted to be secured on substantially parallel with, and slightly removed from the handle, a bag sup-' port adapted to be secured to the upper end of the bag and slidably mounted on the guide and a loop at the upper end of the guide to retain the slidable part at the upward end of its excursion, said bag support containin an extension approximately equal to the ra ius of the cross section of the bag and adapted to be secured approximately to the middle of the upper end of the bag 'in combination with a bag having a substantially fiat upper end.

In testimony whereof, I aflix my signature in the presence of two witnesses this 1st day of Sept, 1916.
